Is this a good modification?

Enzymes A and B use the same resource. Enzyme A is given a higher affinity for it and used in a smaller amount.

Target function, enzyme A 0.903 → 1.159 µmol/L/h +28 %

Shared resource

µmol/L/h	Initial	Modified	Minimum
Target function	0.903	1.159	0.800
Partner function	0.918	0.735	0.800

The modification fails: enzyme A takes more of the shared resource, so the partner function falls below its minimum.

What changed?

Less of the shared resource reaches enzyme B: its function falls from 0.918 to 0.735 µmol/L/h, under the 0.800 required. With more of the resource, both requirements are met.

See the calculation

Model: Two enzymes drawing on one shared resource.
Change: Enzyme A: higher affinity for the resource, smaller amount.
Requirement: Each function at least 0.800 µmol/L/h.
Output: Production of each function, before and after, at two levels of the resource.
Engine: Barzakh Engine 0.140, recorded result.

Synthetic case. Precomputed result.

Measure first, or plan for the delay?

A preparation must produce a set quantity before a deadline, and its activity is too low. The options: replace the enzyme, supply the missing resource, or measure first and then choose.

Measurement result arrives after

Compared with 6 minutes, the starting preparation needs an extra reserve of active enzyme to reach the target in time.

Barzakh Engine chooses the preparation, the measurement and the follow-up action together.

Synthetic case, computed separately from the first. Precomputed result, Barzakh Engine 0.140.
